Dwelling heater installation



Patented June 24, V193() FRAN-K A. HOWARD, or ELIZABETH,NEWlruraissin?,V LAss/rencia imo 'sTANnAEnoaL DEVELOPMEN COMPANY, .A`CGBPO-RATIONQF @EDAWA'RE i* :DWELLING HEATER Yf1 lvsrALriArjIo1r rlhisinvention relates to dwelling heater installations utilizing liquid`fuels and comprehends broadly the combination of a burner for liquidfuels, a means for compressing gas operated inconjunction therewith, areservoir for liquid fuel and an air lift to trans-A fer fuel from saidreservoir to a smaller recep tacle from which the burner is directlysupplied.

rlhe drawing is a diagrammatic vertical Vcross sectionof a preferredembodiment of air'or any othermaterial gaseous at ordinaryl temperature."Preferably, burner 2 operates through the atomization of a liquidfuel'by means of a compressed such asair or recycled flue gas; 'themotor and compressor are preferably designed for this purpose andoperate'when gas is required for atomization.

lf the motor and `compressor are not re'- quired for this purpose, theymay, neverthe- Vlo less, be adapted to operatey simultaneously i withthe burner.

A supply of fuel'for the burner is retained in the storage tank 6,vpreferably ,underground," which may be refilled by means of pipe 7terminating at Vthe ground leveland sealed bythe vented removable plug8. Thev liquid hydrocarbon fuel flows from '6 through pipe 9 into thesump 10 covered by plate 11'. The storage tank 6A 'and sump 10.Vformto#` gether the Asource `of oil supply for there.- Y ceptacle 18situated at the higher level. .The

pipe 12 projects downwardly into nthis sump and at the other `enddischarges into the re` ceptacle 18. Compressed gas required Vfor theoperation of the burner is carried to control mechanism 3 vby means ofpipe 13 con# trolled by valve 14. ik part of the-gas is div verted bymeans of pipe 15 controlled by valve `16. This pipe is provided withbend 17 or equivalent device such as a check Valveto 50 prevent the liowoflfuel by gravity'into the compressorlw'hen lnot in operation. ffthe i'motor andcompressor areinot required for Vthe yoperation, oftheburner'but are adapted to operate.simultaneouslytherewith, the pipe 13may be dispensed with and sealed off.

The pipe ldischarges'the compressed gas into pipe 12 in sump l() or intosuch relationshipv theretothat a mixed column of gas and oil is'formedin pipe 12 of lesser hydrostatic i head than the column ,of oil in thesump,` thereby causing a transfer lofoil to the receptacle 18, The' pipe12 terminates within theV receptacle 18L in the floateoperated'shutovalve 19 whereby the amount y"of oil introduced may be restricted tothat necessary to maintain ade'finite levelA in 18. Gas entering `withthe "oil maybe vented through the pipe V19V controlled by valve 20. lThefloatv oper-v ated shutoif valve `maybe dispensed with in I which eventany excess of oil over that neces- 1 sary to maintain the desiredlevel-in 18 returns through pipe 21 controlled by 'valve 22communicating with thereservo'ir. The pipe `23 controlled yby'valve 24connectswith the receptacle 18 at or nearthe lower part therej of andconducts liquid fuely byV gravity to the burner control mechanismv 3 bywhich it is supplied tothe burner 2.

ItV will be understood .thatthe equipmentv shownis `in Villustratitmand, not` in limitation and, that variousalterna-tives maybe adopti' edwithin the' scope of the' appended claims" `in which it is myV intentiont'oclaim broadl all novelty inherent in the invention. Y

Iclaim; Y

1.,.An oilsupply system for Voil burners VVcomprising a source ofl oilsupply, a recepta-V cle atk a. level above the source lof deliveryA pipeextending into the supply adjacent the'bottom thereof and comsupply a`municating with the receptacle, a Source for supplying gas underpressure, means for discharging gas from the source of gas to thedelivery pipeadjacent the llower end thereof and beneath the level ofoil in said oil supply sourceywhereby a mixed columnV of'gas and oil 'isformed in the deliveryV pipe of lesser `hydrostatichead than the columnof oil in the oil supply source andtheoilfis caused to flow` to thereceptacle, and a pipe to Vconduct oil source vof v y Vluy gravity fromthe receptacle to the burner.

2. Apparatus according to claim 1 in which the source of oil supplycomprises an oil reservoir a sump into which the delivery pipe extends,and means allowing the passage of oil from the reservoir into the sump.

3. Apparatus according to claim 1 in Which the receptacle is providedWith a vent pipe.

4. Apparatus according to claim 1 in which a pipe connection is providedto allow the return of surplus air and oil from the receptacle to thesource of oil supply above the oil level therein. v

5. Apparatus according to claim 1 in which a float operated valve isprovided in said'receptacle to control the fuel introduced in relationto the level of fuel therein. FRANK A. HOWARD.
